WINDOW-SCFiEENi l i specification.

. My invention relates to certain new and useful improvements m Window-screens, and

more particularly embodies an improvement on the screen shown in my Patent N 0.

787,181, granted April 18, 1905.

Generically, my present invention comprehends an improved device .for fastening the screen-wire 'to the screen-frame, which is readil'y removable for the wire when worn.

With other objects in .viewthan have heretofore been specified the ,inventionalso purposes of replacing comprises certain novel construction and com inationof parts, all of'which will be hereinafter full described -pointed out in the appended c aims, and illustrated-in-the accompanying drawings, in'which a Figure 1 is a perspective view of a screen embodying my invention. .iFig. 2-is'adetailcross-sectional perspective of one form'of my the manner of securing similar to Fig. 2 ,showingx'a modified. form of my invention. Fi is a detail perspective view of a portion 0 the screen similar to Fig.

2, showingafurther modification of my in-,

vention. I

, Referring now the accompanying drawings, in wh ch like numerals .0 reference indicate like parts in all ofthe figures, the screen-wire 18 indicated by 1 andthe frame by2.-

The screen-frame-is 'composed. of sheetmetal members and formediin-twoiparts, the

mainsheet-metal frame portion-3 comprising a flat bottom portion-3" and parallel sides 3* and 3, the said side 3P-ha'ving its upper edge 3 bent over at anzangle to the side 3, as shown, while the side 3 has its upper edge 3 bent over at an'angle thereto toward the opposite side 3 as clearly understood from the drawings.

In the form of iny invention shown in Fig. 2 the edges 3 and 3 may lie in slightly-converging planes, which are shown exaggerated in the drawings for purposes of illustration.

4 designates the usual stiffening-rod, which is held between the sides 3 and 3 and the Specification of Letters Patent.

' Application filed February 23, 1908.. Serial No. 302,518.

cross-section, as shown, to ena 1g. 3 is a view of-the parts shown in Fig. 2, separated. Fig. 4 is a view Patented Oct. 30, 1906.

v bottom 3 and bent-over portion 3 of the frame, as shown in my inbefore referred to.

5 designates a substantially U shaped locking memberconsisting of the sides 5 and leg portions 5 5, which in practice may be made slightly divergin as shown in Fig. '2.

The screen-wire whic is clamped between the side 3 and the upper edge 3 of the frame by the U-shaped memberi5, which member 5 and the member 3 are so arranged as to informer patent here- I terlock with'each other andhold the screen securely in place, the extreme edge 3' of the bent-over portion 3 of the frame being so arranged as to'project the screen-wire in a plane parallel with or slightly beyond the side 3 of the member 3, so as to form a watershed.

In Fig. 4 I have shown a slightly-modified form of my invention in which the edge 3 is curved to follow theoutline of therod 4, while in Fig. 5 thelegs 5 5 of the U shaped securing member 5 are slightly curved in le the easy and quick assembling of the parts.

From practical experience I have found that by constructing the screen ,as herein shown and described I am enabled to manufacture the same more cheapl than the screen disclosed in my patent ereinbefore referred to, andbyforming the edges 3 and 3 as described and using the U-shaped member I am enabled to more quickly attach and detach the screen-wire for purposes of renewing the same, &c.

-.The free edge of the portion 3 curled up, as at 3?, if desired, to form-a nard.

Fromthe' foregoing-description, ta en in connection with the accompanying drawings, the complete construction, operation, and arrangement of parts will be readily understood by it-ap ertains. W at I claim is 1. A window-screen comprising aframe consisting of two sheet-metal members, one of which comprises a flat bottom portion and parallel side por ions of unequal lengths, each of said side portions terminatin in a bent-over portion projecting-tower the other side ortion, a'screenwine adaptedto be interlocl de sheet-metal member 'comprisin a U-shaped interlocking member for inter ocking with the bent-over portions of the first-mentioned frame member to clamp the screen between may be those skllled in the art to which d.-with said frame, and the other such first-mentioned frame member and the U-shaped locking member, substantially as shown and described.

2. A metallic window-frame including side, top and bottom portions being composed of a pair of sheet-metal strips, one of said strips having a bottom and parallel side portions, said side portions being of unequal lengths, the upper edge of each side portion being bent inwardly toward the other side portion and spaced-apart, the second sheetmetal strip being of substantially U sha e in cross-sectlon to interlock with the first s setmetal strip and a screen-wire held between said sheet-metal strips and interlocked thereby, substantially as shown and described.

3. Ina metallic window-frame, a springmetal frame-section having a base and parallel sides, said sides being of unequal length, the upper end of one of said sides being bent inwardly at an angle thereto, the u per end of the other side being bent inwar ly at an an le thereto, a locking member composed of a s eet-metal strip havin a straight face and a pair of bent-over e ges to cooperate with the bent-over edges of the first-mentioned frame-section, and a screen-wire secured between said spring-metal frame-section and said locking member, substantially as shown and described.

4, A window-screen comprising a frame consisting of two sheet-metal members, one of which comprises a flat bottom portion and parallel side portions of unequal lengths, each of said side portions terminating in a bent-over portion projecting toward the other side portion, a screen-wire adapted to be interlocked with said frame, and a U- shaped interlocking member for interlocking wit the bent-over portions of vthe first-mentioned frame member toclamp the screen between such first-mentidned frame member I and the U-shaped locking member, the bentover portion of one of the side portions tel minating in a curled edge, substantially as shown and described.

5. A metallic window-frame including side, top and bottom portions, being composed of a pair of sheet-metal strips, one of said strips having a bottom and parallel side portions, said parallel side portions being of une u'al length, said side portions having inwar ly-bent portions spaced apart, the second sheet-metal strip being of substantially U sha e in cross-section to interlock with the first s eet-metal strip between the bent-over portions thereof, a screen-wire held between said sheet-metal strips and interlocked thereby, substantially as shown and described.

6. A metallic window frame including side, to and bottom portions being composed o a pair of sheet-metal strips, one of said strips having a bottom and parallel side es4,44e
